TD-E1-16*FX0-FXS-MUX 16 Voice POTS (FXO/FXS) over E1/G.703 multiplexer provides conversion between ITU-T G.703 standard E1 framed interface and 4 fast ethernet+1~16 voice POTS FXO/FXS interface, can through E1 channel provide 1-16 voice, realize the long-distance extend of telephone line through E1 channel. It also provides one RS232 data channel.The16 voice POTS FXO/FXS over E1 multiplexer can automatically connected to the LAN with its uninterrupted learning the MAC address and the address as another purpose of the frame relay LAN. The 16voice and Ethernet to E1 interface converters widely used for LAN and Wan networking, control, and so on, and particularly applicable to the network users to the network users with a single E1 channel access data and voice at the same time.


          Realizes long-distance monitoring of local device to the remote device based on self-copyright IC;

          Provides two clock types: E1 master clock, E1 line clock;

          Support SNMP for option

          Realize the automatically rate set of local device to remote device

          has the function of pseudo-random code testing, convenient for opening of the circuit, and can be used as an error code instrument;

          E1 supports 75Ω unbalanced and 120Ω balanced impedance at the same time;

          Provides 16 voice channels, support calling indication

          Voice port supports O port and S port, O port connects switch and S port connects user’s phone;
